Transfering files with SCP command

Hi!
I wanted to transfer files from my working computer to webminal.
I recollected my previous topic about SSH connetion and tried to transfer file inputdictionary.txt using SCP command and port (which had been mentioned by you in the topic about SSH connetion):

PS C:\Work\Pavel\Per\Англ> scp .\inputdictionary.txt -p40978 root@webminal.com:~
The authenticity of host 'webminal.com (169.48.152.64)' can't be established.
ECDSA key fingerprint is SHA256:qdQBfk747BqDvHIxrktKsRw14wgqaGcQ0vlwTTG/uSo.
Are you sure you want to continue connecting (yes/no)?
Please type 'yes' or 'no':
Warning: Permanently added 'webminal.com,169.48.152.64' (ECDSA) to the list of known hosts.

lost connection

May be something should have been fixed on webminal or it’s my incompetence?

Can you try with

-P40978

instead of -p and check the results?
